EF 7 Beta 8 -> EF7 RC1 - No longer can create migrations - asp.net-core

After attempting to change my existing project from beta 8 to RC1 I get the following after running dnx ef migrations add Init
System.TypeLoadException: Could not load type 'Microsoft.Data.Entity.Scaffolding.SqliteDesignTimeServices, EntityFramework.Sqlite.Design'.

Could not load type 'Microsoft.Data.Entity.Scaffolding.SqliteDesignTimeServices, EntityFramework.Sqlite.Design'.
My project.json file contains along with others the following
"dependencies": {
"EntityFramework.Commands": "7.0.0-rc1-final",
"EntityFramework.SQLite": "7.0.0-rc1-final"
},
"commands": {
"ef": "EntityFramework.Commands"
},
What do I need to do to resolve this error?

Package names are case-sensitive on Linux and OS X due to the case-sensitive filesystem. Make sure to use EntityFramework.Sqlite not EntityFramework.SQLite in your project.json file. (See GitHub Issue dotnet/cli#236)

First resolve your references / dependencies. All reference warnings must be solved and must be "7.0.0-rc1-final".
If there is no "7.0.0-rc1-final" version then probably something is renamed to a different name. See the annoncement repro for breaking changes
"dependencies": {
"EntityFramework.Commands": "7.0.0-rc1-final",
"EntityFramework.SQLite": "7.0.0-rc1-final"
},

Getting "Can't find custom atter constructor image" from a .dll after upgrading to Unity5

I've just upgraded to Unity5 and a small .dll I've made started to give the following error:

The .dll worked perfectly before updating to Unity 5, and I did recompile the .dll with the unity5 version UnityEngine.dll (needed by my library), but that didn't help. Any ideas how to fix this?

Creating Roslyn MetadataFileReference bombs on mono/Linux

I'm doing on some basic Roslyn stuff, and have run into what appears to be a mono compatibility issue. Wanted to make sure I'm not doing something wrong and hear other people's experience. Am using Roslyn from the Microsoft.CodeAnalysis nuget, version 0.7.4091001-beta (latest).
var mscorlib = new MetadataFileReference(typeof(object).Assembly.Location);
var compilation = CSharpCompilation.Create("Temp", new SyntaxTree[0], new[] { mscorlib });
compilation.GetAssemblyOrModuleSymbol(mscorlib);
While this works on Microsoft .NET, on mono on Linux the last line produces the following exception:
[ERROR] FATAL UNHANDLED EXCEPTION: System.ArgumentException: Absolute path expected.
Parameter name: fullPath

There's obviously some sort of path parsing Linux/Windows sadness going on here. My current workaround is to create the reference to corlib thus:
var mscorlibMetadata = AssemblyMetadata.CreateFromImageStream(new FileStream(typeof(object).Assembly.Location, FileMode.Open, FileAccess.Read));
var mscorlib = new MetadataImageReference (mscorlibMetadata);
Does anybody know anything about this?
This is a bug in Roslyn.
You can send them a pull request to fix PathUtilities.GetPathKind to be aware of Linux-style paths by checking Path.DirectorySeparatorChar.

How does one set the filename in Monodevelop?

I have recently installed MonoDevelop V3.0.3.2 on Linux Mint 15 MATE 64-bit.
I installed MonoDevelop through the Software Manager
I attempted to create a new project per http://monodevelop.com/Documentation/Creating_A_Simple_Solution
Unfortunately I receive an error on attempting to build that the filename has not been set. Details of error received are as follows.

How does one set the filename in Monodevelop?
EDIT: The Build of the project is working , Problem is occurring when attempting to run the application in the IDE
I had the same issue. I found out that if you install xterm, and restart monodevelop the error will be resolved. Apparently xterm is a dependency. Just go to terminal and "sudo apt-get install xterm".

Embedded mono + app.config

I have embedded mono in a c++ program and loaded a dll which requires an app.config. I am getting this kind of error, does someone have an idea on how to ship *.config with an embedded mono ?
The stack trace :

Self answer : you can't (as of 2013-04-30). To enable this behaviour, I had to change mono's framework sources mono/mcs/class/corlib/system/appdomain.cs :
public AppDomainSetup SetupInformation {
get {
return SetupInformationNoCopy; // newline
// AppDomainSetup setup = getSetup (); //old
// return new AppDomainSetup (setup); //old
}
}

Mono does not have a compatible version of SlSvcUtil.exe, so you need to use the slsvcutil that Microsoft provides as part of the Silverlight 3.0 Tools to generate the client proxy.
